Thoughts on the Psyker. is ok. (i'm rank 13)
Perks seem like garbage. none really seem very game changing. Almost incoherent any good playstyle.
biggest value for psyker seems like just the fact they free up ammo. haha. 10% damage buff. and dont use ammo with staff, and don't use grenades. I mean, that really is a pretty solid buff for the others.
they need to juggle 3 weapons. which can be rough. With brainblast, being the swap for grenades, and essentially being a 3rd weapon. Brainblast I find to be eehhhhhhhhh. slow cast. High damage at low difficulties. but, doesn't scale. so fails to one shot from what I understand in higher difficulties. which would really make it shit. Slow cast. it does have some interesting target mechanics. left click lock on. infinite range. So you can tag a target at any range, and hold target even if it or you goes behind cover. right click lets you charge it, and instantly release. minor use for dogs, boomers, trappers. but, generates peril while holding. bleh.
I've not really enjoyed any of the staves yet. left click bolt is a slow projectile. middling damage. but too slow for long range attacks. it has little use. The right click charge attacks is their real use. trauma is a ground aoe explosion, which is shit. shock is a chain lightning. weak damage. people on reddit seem to like it for stagger. Personally, Im not feeling it. Rather just melee the hordes, instead of tempting death with the lightning, and its poor damage. we'll see with more perks, better gear.. I got a void staff, which I hear is a charged linear bolt. which I think might be better. I hear its higher damgae. But, dont have the rank to actually use it yet. have not gotten the flame staff yet. That also gets recommendations. but so far, don't love the staves, only don't use guns, due to the ammo thing.
Force sword. What else even is there? Got a Force sword, and have not even looked at the other melee weapons. this thing is the tits. its cleaving is not high teir. but does ok. its force shield block is great. strong aoe push. I think it blocks ranged shots too. Right click special attack. Murder machine. light attack and heavy attack do seem to do the same damage with it. so just use a light attack with it. Massive single hit damage attack. Just murders armor, mutants, bosses.
Force push F. pretty solid too. Ogryn can push deamons off ledges. I don't know if this can. I don't think I've seen it work on knocking deamons back.
Juggle the 3 weapons, and juggle peril.
The mechanics for killing yourself with peril is actually a bit subtle. can be cheesed with practice. only die on offense attack at 100%. force shield at 100% does not kill you. force push with force sword at 100% does not kill you. if brainburst was STARTED at sub 97%, it will not kill you at 100%. 99% for force sword stab.
so, an incredibly frantic juggling of 99% in the middle of combat can be done.. good luck. haha.
